Double Rail Crossbeam CastingThe Cast Iron Parts Of The Crossbeam Are Produced Using Resin Sand Disappearing Mold Technology. In The Resin Sand Process, The Permeability Of Resin Sand Is Crucial, As It Directly Affects Whether The Bed Casting Has Defects Such As Porosity And Cold Insulation.
1. Particle Size And Particle Size Dispersion Of Raw Sand. If The Roughness Is Large, The Breathability Is Low. The Permeability Of Coarse Sand In Bed Casting Is Higher Than That Of Fine Sand.
2. The Lower The Purity Of Alcohol, The Higher The Air Permeability.
3. Mixing Time. Both Too Long And Too Short Will Reduce The Permeability Of The Molding Sand.
4. Tightness. The Higher The Compactness, The Lower The Breathability. However, If Some Corners Are Not Tightly Compacted, Sand Entrapment May Occur.
